The　aim　of　this　research　is　to　build　a　model　to　integrate　the　factors,　such　as　natural,　geographic,　political,　economical　and　social　factor.　And　the　interactions　among　different　factors,　based　on　the　analytical　data　to　anticipate　the　transportation　demands　in　western　China.　The　research　tries　to　build　up　a　systematic　model　and　method　of　transportation　planning　and　arrangement　adjusted　with　the　reality　and　data　of　western　China.　This　research　is　based　on　the　theoretical　research　and　practical　experience,　which　include　logical　framing　(qualitative　model),　mathematical　modeling,　practical　arithmetic.　The　objective　of　the　research　is　to　develop　a　synthesized　model　base　multi-factor　quantitative　analysis.　The　application　of　the　model　will　optimize　the　transportation　and　logistic　arrangement　of　western　China　area.
